Fig. 6 is an en connecting-rods reaching to the cross-bar of larged view of a bearing-box for the gearthe brake in front of the wheels. Said roller brake roller, which box is constructed as a is also provided at one of its ends with the part of the clip-plate that rests upon the usual cranlearm, e, from which proceeds the rco connecting rod, reaching to the hand or foot lever by which the brake is operated, and which is located adjacent to the drivers seat. There is nothing new about the brakein itself, except in the location of the roller E thereof in the position shown. This position of said roller is new in itself, and is found to be particularly advantageous from the fact that it brings the connecting-rods into substantially horizontal positions, while affording the desired length of levers e e, and for the further reason, that said roller is perfectly protected in this position, is entirely out of the way, and may be mounted firmly and securely in the clip-plates of the springs, and will be sustained powerfully against all strains upon the brake by its direct attachment to the rear-axle structure.

The king-bolt present in the wagon shown, and intended to be used in connection with the springbrace, next to be described, is a king-bolt which is jointed or pivoted at or adjacent to the meeting faces of the front axle and bolster, so that the axle may rock beneath the bolster when the wheels of the wagon are moving over irregular surfaces. Such a king bolt is illustrated and described in Letters Patent of the United States, No. 267,327, patented November 14:, 1882, to one of the pres ent applicants, the vertical portion of said patented king-bolt being in this case extended downwardly through the axle, as shown at F, Figs. 1 and 3.

G is the spring-brace referred to, but it may be of other forms than that here shown. It connects with the reach or reaches at its rear end, and is preferablyin U shape, as shown in Figs. 1 and 5, in order to give a longer horizontal portion, 9, so that when the brace yields at this curve 9 the forward end thereof, which connects with the king-bolt F,will have a practically vertical movement instead ot'one more inclined, as would be the case were said horizontal portion of the brace shorter, or the point of flexure in the brace nearer to the axle. The connection of this brace with the king-bolt is essentially like that of braces heretofore employed for the support of the lower end of king-bolts-that is to say, it has a hole through it, through which the king-bolt passes, and beneath it will ordinarily be ap plied a nut or its equivalent, as shown atfin Figs. 1 and 3.

The brace is made of a flat bar or strip of steel, and is constructed to bear upward at its front end against the axle, where it embraces the king-bolt. The rear end of the brace being attached to the reach or reaches, and said reaches being in turn connected witha bolster, H, the operation of the spring will therefore be to press the bolster and the axle together, with the effect of assisting the prompt restoration of the parts to their proper position after the rocking of the axle with respect to the bolster, and prevent the noise which would otherwise proceed from these parts when the vehicle is driven rapidly over uneven roads.

WVhen the wagon has but a single reach, the rear end of the springbrace G may be attached direct-1y to the under surface of said reach; but when the reach is double, as here shown, we provide a metal cross-plate, Lwhich is fastened to the reaches and to the central part of which the springbrace is bolted or otherwise secured. In the form of such crossplate, illustrated in Fig. 5, said cross-plate is provided with front and rear projections, i i, to which the spring-plate is bolted, and at the ends of said cross-plate are projections t",

which run back beneath the reaches and more firmly support the cross plate and springbrace.

\Ve claim as our invention- 1. The combination, with the rear axle and with springs placed transversely to said axle, of a brake-roller occupying a position immediately over and sustained upon the axle, substantially as described.

2. The combination, with the rear axle, springs placed transversely to said axle, and a brake-roller, of clip-plates constructed to afford bearings for the brake-roller and resting upon the springs at their junction with the axle, and clips which secure said clip-plates, springs, and axles to each other, substantially as described.

3. The combination, with the front axle, its.
